Combination weighing device

Abstract

A combination weighing device is provided that discharges, from a hopper, an article oversupplied into and received by the hopper and that collects the article using the collection container. The combination weighing device includes an oversupplied article retainer disposed at a position on a discharge path for the article to be discharged from the hopper and collected by the collection container. The oversupplied article retainer has a collection chute and a blocking shutters and temporarily retains the article guided to flow downward using the collection chute and the blocking shutter.

The invention claimed is: 
     
       1. A combination weighing device, comprising:
 a hopper; and 
 an oversupplied article retainer, 
 the combination weighing device being configured to discharge an excess amount of articles supplied to the hopper and collect the articles in a collection container, 
 the oversupplied article retainer being disposed on a discharge path from the hopper to the collection container and temporarily retaining the articles on the discharge path, wherein 
 the hopper is a weighing hopper that weighs and discharges the article, and 
 the oversupplied article retainer comprises: 
 a collection chute that guides the article discharged from the weighing hopper into the collection container; and 
 a blocking shutter that opens and closes the discharge path in the collection chute. 
 
     
     
       2. The combination weighing device according to  claim 1 , wherein
 the blocking shutter is allowed to linearly move between a discharge path opening position away from the collection chute and a discharge path closing position proximate to the collection chute. 
 
     
     
       3. The combination weighing device according to  claim 2 , wherein
 the oversupplied article retainer comprises: 
 a plurality of the collection chutes arranged next to each other; and 
 a plurality of the blocking shutters disposed correspondingly to the plurality of the collection chutes, wherein 
 the plurality of the blocking shutters are allowed to linearly move all together. 
 
     
     
       4. The combination weighing device according to  claim 3 , comprising:
 a plurality of the weighing hoppers that discharge the articles oversupplied into the plurality of the collection chutes, the plurality of the weighing hoppers being arranged next to each other; and 
 a plurality of linear feeders that supply the plurality of the weighing hoppers with the articles, the plurality of linear feeders being arranged next to each other. 
 
     
     
       5. The combination weighing device according to one of  claims 1  and  2  to  4 , further comprising a movable table on which the collection container is placeable, the movable table being allowed to slide by manual handling. 
     
     
       6. The combination weighing device according to  claim 5 , further comprising a plurality of mirrors disposed in a manner that inside of the collection container is externally viewable. 
     
     
       7. The combination weighing device according to one of  claims 1  and  2  to  4 , further comprising a plurality of mirrors disposed in a manner that inside of the collection container is externally viewable.
